HYDROCARBON-VAPOR INCANDESCENT LAMP.

SPECIFICATION forming part of Letters Patent No. 714,947, dated December 2, 1902.

Application filed September 4, 1900. Serial No. 28,883. (No model.)

In the setting device K, I provide a pas- 50 F is a pipe or inlet connected with a source sage T, communicating at one end with the outer chamber J of the vaporizer, a deflector L being provided, if desired, to direct the current of vapor upwardly and which acts as well to remove particles of carbon from the vapor, since they will strike against it and fall back into the end of the vaporizer. (See Fig. 1.) At the upper end passage T communicates through a valve U with the interior of the mixing tube or chamber V. An opening X to the outer air behind valve U enables the vapor to draw atmospheric air freely with it into chamber V,t'rom the opposite end of which the mixed air and gas flows into a fixing and superheating drum W. A double deflecting-surface Y may be arranged opposite the inner end of chamber V to direct properly the mixed air and gas into the superheating-drum. From the drum IV passages Z Z furnish communication with the burners D in the ordinary manner.

The cock G is turned on slightly to introduce a small flow of fuel into the auxiliary burner N, and at the same time the electric circuit Q is closed, so as to heat the platinum core R, which being confined in the tube N is readily heated to incandescence, and thus lights the burner N. On turning the cock G hydrocarbon oil is allowed to flow into the inner passage H of the vaporizer M, thence (following the arrows in Fig. 3) through the middle and outer chambers I J, which are closer to the source of heat, thereby being subjected to a temperature which rises gradually to the point of vaporization of the oil. The vapor thus produced expands outinto the passage T, any particles of carbon carried by the gas tending to drop in the pocket behind the deflector L. From the passage T the gas forces itself through the port U (which may, if desired, be provided with a needle-valve, as will be understood readily) and into the mixingchamber V, drawing with it air admitted through the opening X. The vapor, being mixed in the drum V, dried, and further heated in the superheating-drum W, feeds downward continuously through the passages Z Z to the burners D D, where it is lighted as it rises by the flame of the burner N. As soon as the burnersD are lighted they operate the vaporizer and the auxiliary burner may continuous and gradual vaporization of the oil and to facilitate its removal when necessary for cleansing, the provision of deflectors L andYto direct properly the flow of the vapor, the provision of means to remove particles of carbon from the vapor, the addition of an automatic lighting device and of safetyscreen S therefor for the auxiliary burner N, and the arrangement of this burner N to heat as large an area as may be of the vaporizer.

I do not desire to limit myself in any way to the details of construction of the various parts described, as I consider them capable of modification in various ways from the types illustrated in the drawings.

What I claim as my invention is 1. In a hydrocarbon-vapor lamp, the combination with the burner, of a vaporizer above the burner, a mixing-tube adjacent to the vaporizer, and a superheating-drum concentric to the mixing-tube in communication therewith and with the burner, as and for the purpose set forth.

2. In a hydrocarbon-vapor lamp, the combination with the burner, of a vaporizer comprising a series of intercommunicating chambers, a mixing-tube adjacent the vaporizer, and a superheating-drum concentric to the mixing-tube in communication therewith and with the burner, as and for the purpose set forth.

3. In a hydrocarbon-vapor lamp, the combination of a vaporizer comprising a series of intercommunicating chambers gradually approaching the source of heat, a mixingchamber communicating with the last of the chambers of the vaporizer, a superheatingchamber arranged concentric to said mixingohamber, and passages leading from said superheating-chamber to the lamp-burners,sub stantially as and for the purposes described.

4. In a hydrocarbon-vapor lamp, the combination of a vaporizer, a removable setting device for locating and supporting said vaporizer, a passage through said setting device communicating at one end with said vaporizer and at the other with a mixing-chamber,

and a deflector between said vaporizer and said setting device, as and for the purpose set forth.
